Show git diff on file in staging area

GitGit DiffGit Stage

Git Problem Overview

Is there a way I can see the changes that were made to a file after I have done git add file?

That is, when I do:

git add file
git diff file

no diff is shown. I guess there's a way to see the differences since the last commit but I don't know what that is.

Git Solutions

Solution 1 - Git

You can show changes that have been staged with the --cached flag:

$ git diff --cached

In more recent versions of git, you can also use the --staged flag (--staged is a synonym for --cached):

$ git diff --staged

Solution 2 - Git

In order to see the changes that have been staged already, you can pass the -–staged option to git diff (in pre-1.6 versions of Git, use –-cached).

git diff --staged
git diff --cached

Solution 3 - Git

You can also use git diff HEAD file to show the diff for a specific file.

See the EXAMPLE section under git-diff(1)
